 |

Don- do you see a VM code generation problem with the code where right() is called? When I use right() in this manner with fmt(), the VM hangs. Using a constant like 1.234 instead of a var like "sec" yields the same error.
If I put the resultant string from fmt() into a local var, then use that var with right(), no hangup.

I see the problem. You have correctly identified the workaround - using a temporary variable to hold the value returned from the function instead of passing it directly.
A solution has been derived. Although we are approaching the cutoff for a new release, we'll probably be able to get the change through testing before that time.
Thanks. |
